HAROLD J GOSS, OF N ASHUA, NEW HAMPSHIRE, ASSIGNOR, BY MESNE ASSIGNMENTS TO THE LAKE ERIE TRUST-COMPANY, OF CLEVELAND, OHIO, A CORPORATION OF MACHINE FORJMAKING: SET-UP BOXES.

Application filed June 26, 1923. Serial No. 647,849.

To all ilk/tom it may concern:

Be it known that I, HAROLD J. Gross, a citizen of the United States, and resident of Nashua, in the cou ty of Hillsborough and State of New Ham shire, have invented certain new and useful Improvements in Machines for Making Set-Up Boxes, of which the following is a specification.

This invention relates to the manufacture of paperboard boxes and has particular reference to machines for making rectangularboxes in setup form, ready to have goods placed therein. The boxes of this type are referred to as wall boxes for the reason that they present upright side portions which serve as walls to retain goods.

The object of the invention is to provide an improved machine which is rapid and automatic in operation, the blanks being fed sin l and successivel to the machinefolded therein, and delivered therefrom in firmly set up condition.

With this object in view the invention consists in the construction and combination of parts substantially as hereinafter described and claimed.

Of the accompanying drawings: 7 I Figure 1 is a perspective view of the machine, omitting details of some parts to avoid confusion. said omitted details being illustrated in other figuresf Figure- 1 is a detail perspective view of theblank pushing finger at the end of one of the sliding rods.

Figure 2 represents a longitudinal section of the machine, omitting some portions thereof and some portions being part y broken out.

Figure '3 is a detail plan view of the mechanism for squaring up the blanks after they leave the feeder. to ensure straight travel through the gluing and folding mechanism; the middle portion of said mechanism being-broken out 'to reduce width of the figure.

Figure 4 is a detail perspective view of a i 0 the plunger mechanism whichv effects conidition.

Figure 5 represents a section on line :'-5 of Figure2, on a larger scale. Figure 6 represents a section on line -(3 of Figure 1 on a larger scale.

Figures 7, 8, 9, 10, 11, 12 and 13 are perspective views illustrating successive'operations on a blank passingthrough the machine.

Similar reference characters indicate similar parts in all of the views, numerals being employed for the machine, and letters for the blanks being operated upon.

A suitable frame 12 is provided with brackets 13, the latter having bearings for the shaft 14 of feed wheels 15. The blanks, which are supported by a table not necessary to illustrate, are drawn successively over retards 16 (Figs. 1 and 2) adjustably mounted on a tie rod 17, and are fed over rolls 18 carried by arms 19 the hubs 20 of which are pivotally mounted on the tie rod 17. Said hubs have tail pieces 21 to which springs 22 are connected to cause the rolls 18 to bear yieldingly against the combing feed wheels 15. This construction enables each roll 18 to yield relatively to the combing wheel 15 above it independently of the other roll 18, to aid in forwarding the blanks without their turning askew;

Extending longitudinally of the machine (Figs. 1, 2 and 5) are two parallel bars 23 mounted on tie rods 24 so as to be laterally adjusted thereon. Idly mounted in' line with the front end of each bar 23 is a sprocket 25. Inline with the rear ends of said bars are. sprockets 26, carried by a driven shaft 27. Mounted onthe four sprockets and riding along the upper edges of the bars 23 are two chains 28 having spaced pins 29 to engage the rear edges of the blanks as hereinafter described. Each chain is laterally guided by ribs 30 of the bars 23 (Fig. 5). Strips 31, the upper edges of which are substantially flush with the tops of the ribs 30, are located between the bars 23, being supported by posts 32 mounted on tie. rod 33 and on one of the tie rods 24 and secured in proper lateral position thereon by set screws 34. A pair of upper guide strips 35 are carried by rods 36 which project in' ward from brackets 37 supported as hereinafter described. plete folding of the blanks to set up con- To effect the application of glueto selected portions of each blank as hereinafter described, I provide a. pair of glue boxes 39 each having a roll 10 for a film of glue.- A guide or pressure roll 41. is yieldingly mounted above each roll 40.

The machine constructed as illustrated is designed to operate on blanks each of which, when flat, (Fig. 7) consists of a middle portion a to form the bottom of a box, end wall sections 6 the outer edges of which are straight, and side wall sections 0 having flaps d which are of the same length substantially as the sections b but with ogee shaped tips as shown by.Figure 7. The machine is not, however, limited in its use to folding blanks of this specific shape.

In order that each blank may be centralized as it leaves the feed wheels, and preferably just after its rear edge is engaged by a pair of chain pins 29 to push it along, I employ devices which, for convenience, I refer to as joggers. As shown by Figures 1, 3 and 7, two parallel rods 42, 43, are mounted to have a short sliding movement in the flame of the machine, and they carry i a blank to central position.

two upright wall members 44 each having a horizontal shelf 45 one end of which, onto which a blank rides, is curved downwardly. Each device 44, 45, is carried by the upper edge of a pin 46. One of these pins 46 rises from a block' 47 which is adjustably clamped to the rod 42 and slides on rod 43, and the other pin 46 rises from a block 48 which is adjustably clamped to rod 43 and slides on rod 42, so that as the rods slide in opposite directions the joggers move toward and apart from each other, the blocks being so adjusted relatively to each other that one or the other will push As will now be described, the two rods 42, 43, are automatically actuated to cause the distance between the two jogger walls 44, .when reachin their limit of movement toward each other, to just equal the width of a blank. And the timing of operation is such as to cause the joggers to act against the straight outer edges of the sections 1) of the blank. The rods 42, 43, are normally held with the joggers at their outer or spread limits of movement by a spring 49 (F ig. 3) under compression between two abutments 50 each of which is secured to one of the rods. I shall now describe the means for shifting the rods to cause the joggers to act as indicated in Figure 7. Adjustably secured to each rod 42, 43, is a roll 51 (Figs. 1 and 3). To spread the two rolls 51 apart at the proper times so as to slide the rods in opposition to the spring 49, I e1n ploy a wedge 52 carried by-a lever 53 pivoted at 54 and having a roll 55 actuated by a cam 56 carried by the shaft 14, a suitable spring 57 being employed to effect return movement of the lever. The timing is such that the wedge causes the two joggers 44 to approach each other each time that the feed rolls have advanced a blank to the position indicated by Figure 7 and a pair of chain pins 29 have engaged its rear edge. During such advance, the blank travels in the direction of the arrows in Figures 3 and 7, its marginal portions riding onto and over the little shelves 45 of the oggers.

After the ogging or squaring up operation, the portions 5 are broken down in order that only the flaps (Z, and the under surfaces thereof, will receive glue from the rolls 40. To break the portions 6 down, I employ arms 58 carried by a shaft 59 having a sprocket 60 (Fig. 1) connected by chain 61 with a sprocket 62 carried by the shaft 14. These connections are such as to efi'ect a timing that will, just after the blank has advanced from the position shown by Figure 7 to the position shown by Figure 8, cause the rotary depressing arms 58 to break the sections 6 on their crease lines so that as the blank continues to advance, the sections 6 will be deflected below and inside of a pair of guide fingers 63 supported by a universal joint connection 64 (Fig. 1) with a. suitable portion of the machine such as a rod 65. The rod 65 extending from each glue box supports, by a universal joint connection, a finger 66 the far end of which leads onto the top of the glue box. The fingers 63, 66, are adjusted to such inclinations that, as the blank is pushed along, the two sections b b which have been depressed, by the rotary arms 58, are guided down to substantially vertical positions inside the glue boxes and against the surfaces of the inner walls of the two glue boxes 39 and consequently receive no glue, while all four of the flaps 01, (Z, since they are not acted upon by the rotary depressing arms, pass above :the fingers 63 and fromthem onto the fingers (S6, and from the latter onto the glue boxes and over the glue rolls 4O as-indicated in Figure 9. To enable the downwardly turned sections 1) b to pass along, the glue boxes are slightly spaced away from the outer surfaces of the bars 23 as indicated in Figure 5. The fingers 63, 66, are omitted in Figure 9, but their position relatively to the glue boxes is clearly shown in Figure 1.

After the blank has been advanced by the chain lugs or pins far enough so that the under surfaces of all four flaps d d have received glue from the rolls 40, its movement is accelerated by mechanism which not only separates its rear edge from said lugs so that the said lugs will not'tear notches in said edge when the lugs pass down around the sprockets 26, but also pushes the blank to the position where it is to be folded. Said mechanism comprises a pair of rods 67 (Figs. 1, 1, 3, 5 and 10) mounted-to slide in bearing blocks (58 secured to the bars 23 and actuated as presently described. Each rod 67 at its front end (Fig. 1) has a block 69 in which is pivoted, at 70, a finger '71 having a' notched front end. A spring 72 normally holds the fingertitled slightly upward with its notch in the plane of a blank. (hen the two rods move back, their two fingers will readily swing down so as to freely pass back under a blank, and after-so passing back, the fingers will spring up so their; notches will be'in position'to engage the rear edge of the blank under which they havejust retreated, and to push that blank forward when the rods slide forward (Fig. 110.).

The mechanism for reciprocating the push rods 67 comprises a rock shaft 73 (Figs. 1 and 2) having two long arms 74 connected at-their upper ends'by a small cross rod 7 Each push rod has a block 76 secured to it, a pin 77 extending'downwardly from it into a socket 78 mounted on the cross rod 75, whereby rocking movements of the shaft 73 transmit sliding movements to the push rods through the arms74 and the pins 77. The rock shaft is actuated by a cam 79 carried by a shaft 80, and a link 81 having a roll 82 engaged by the camand connected to a short arm 83 of'the rock shaft 73, a suitable spring being employed to hold the roll 82 in contact with the cam.

The throw of the arms 74 is such that when they move to the position indicated onto.

in Figure 2, the notched fingers 71 of the slide rods push the the blank to position to position by a pair of stops 84 adjustably mounted in blocks 85 which, in turn, are" laterally adjustable'on a tie rod 86. Each stop 84 carries a ledge 87 having a bevelled tip for the 'front edge of the blank to ride As the blank is pushed to position a ainst the sto )s it rides under a )air of spring fingers 88 carried by a cross rod 89 mounted on theupper guide strips 35 (Figs.

' 1, 2 and 10). These fingers are so mounted that their free ends are above the ends of the wide strips 31 and bear lightly on the.

blan to prevent it from rebounding from the stops'84 (see Fig. 2). at substantially rigid inclined finger 90 is also mounted on the cross rod 89 in position toprevent the mid-width portion of the blank from curving up or bulging due to the sections 6 b being held down as the blank'is pushed to position across the plungers presently described. To hold said sections b 6 down as just mentioned, a uide rod 91 is employed on each sldejextending as indicated ill-Figs.

1 and-10, and connected by an adjustable 1 I clamp 92 with a rod 93 projecting outwardly support the nae. two tie rods 94 (Figs.

.ent lengths of boxes.

1' and 2) extend across from side to-side of the frame of the machine. Front and rear wall plates 95, having outwardly curved lower ends, are rigidly carried by lugs 96 which are slotted and have screws extending into blocks 97 Which are ad ustabIy mounted on the tietrods 94. The slotted lugs 96. and the screws enable the plates to be adjusted to suit dilferentwidths of boxes to be 7 made, and the adjustable mounting of the blocks 97-0n the tie rods provides for differ- Four of the plates 95 are provided with vertical slots through I which yieldingly mounted members 98 project to serve as strippers ashereinafter explained.

At each end of the box-forming chamber 9 is a pressure plate 99 havingan inwardly.

projecting ledge 100 at its upper edge.

Each plate 99 is carried by a slide'101 sure plate, and an anti-friction roll is 7 supported by the frame behind each cam to sustain the pressure when the two plates 99 are acting on the ends of the box as hereinafter described. 'be folded, the blank being arrested in that Each shaft 104 has a sprocket 106 (Fig. 1) driven by a vchain 107 from a sprocket 108 carried by the shaft 80. Suitable springs 109 effect outward movement of the .illustrated by Figure 11, when the compound plungers which will now be described 1 \i-ise and life the blank.

To guide the plunger mechanism vertically (Figs. 2 and 4) bearingblocks 111 are mounted on tie rods 112. A plunger 113 having a recessed upper face, with bevelled end edges 114 (see also Figure 13). has a channelled stem 115 mounted. to slide in the blocks 111. A flat-surfaced plunger 116 has its stem 117 mountedto slide within the channelled stem 115.

A' rock shaft 118 (Fig. 2) has two-arms 119 (Fig. 4) connected by links 120 to op posite sides ofthe channelled stem 115 and has another arm 121 carrying a roll 122 which is acted upon by a cam 123 carried 110 to a i by shaft 80.- A rock shaft 124 has an arm 125 connected by a link 126 to the stem 117 and has anotherarm 127 carrying a roll 128-which is acted upon by a. cam129 also carried by shaft 80. Suitable springs such as indicated in Figure 2 may be employed to ensure prompt return movements of. the rock shaft arms. The cams 123, 129, are omitted from Figureil because they are at the far end of shaft and to include them in that figure would confuse other parts.

The shaft 80 has a gear 130 (Fig. 2) meshing with a pinion 131 carried by a stud shaft 132, said shaft having a gear 133 driven by a pinion 13% carried by the main shaft 135 of the machine.

Some of the driving connections which are shown in Figure 1 are not described because they are not important and may be diiierent from the illustration.

in operation, each blankfed by the combing wheels 15 arrives on the ribs 30 of the bars 23 (Fig. 7), the timing of operation of the combing wheels and the chains 28 being such that the rear edge of the blank arrives somewhat in advance of a pair of chain pins 29. The friction between the blank and the ribs 30 retards the blank un til said pins engage its rear edge. lmmediately after such engagement and the consequent pushing of the blank along, the joggers d4 approach'each other and centralize the blank. As the blank then proceeds, its

end wall sections 6 b are broken down by the rotary depressers 58 (Fig. 8) and pass under the fingers 63 and then along against the inner walls of the glue boxes 39 (Fig. 9). The flaps (Z d however are not deflected down and they pass over the glue rolls, and

receive glue on their under surfaces. 'DUYP ing this portion of the forward movement of the blank the sliding push rods 67 are-retreating until their notched fingers 71 can spring up behind therear edge of the blank, and then the rods move forward and accelerate the advance of the blank pushing it under thespring fingers 88 (Fig. 10) and against the stops 84 (Fig. 2). plunger 116 rises, immediately followed by the plunger 113, lifting the blank in such manner that, while the sections 6 b are held down and partly in by the bent guides 91 (Fig. 11) the'sections 0 c are swung toward each other by riding against the inner surfaces of the outwardly curved lower ends of the plates 95. At the same time the flaps (Z (l are bent on their crease lines by the guides so that as the blank continues to rise, the said flaps, having cleared the'guides 91 (Fig. 12) approach each other edge to edge outside of the sections b. 6, ready to have their inner glue-carrying surfaces pressed against said sections b b, when the blank is raised still higher entirelyabove the upper edges of the guides 110 in Fig. 12.

As shown by Figures 4, 12 and 13, there is a ledge 186 projecting from each end of the plunger 113 at the bottom thereof. When the blank is in about the position shown in Figure. 12, its flaps d d are folded in above the ledges 136. At this time the,

plunger 113 has not caughtnp with the plum or 116 and therefore there is room for the aps to be so folded. the blank is Then, the

moved up to the position shown in Figure 13, between the end pressers 99 which now move in, the plunger ledges 136 push the flaps d d int-o alinement and cooperate with the ledges 100 in causing the now top and portion considerably higher than the other .as indicated in Figure 2, which higher ,por-

tion eilects the last mentioned discharging movement of said plunger 116.

The completed box is caught by the strippers 98 and rests thereon until the completion of another box, and the lifting thereot,

effects its displacement by pushing it up clear of the plates 95. To cause each box, as it emerges from the top of the chamber between the plates 95, to tilt in a predetermined direction into any suitable delivery chute, 1 provide a pair of curved spring deflectors 1337 (Figs. 1 and 2) mounted on two of the slotted plates 96.

To avoid any possibility of a blank shifting laterally or turning askew as it is pushed to position to be acted upon by the h plungers, 1 provide a pair of side guides 138 (Figs. 1 and 2) adjustably mounted at one end on the tie rod 86 and having their other ends somewhat flared to admit the blank between them.
